Help! Will lubricant affect spkr.cables?


My H.Tech. Pro-9 bi-wire speaker cables are a very tight fit when trying to slide them up inside my B&W speaker stands. If I put some lubricant on the outside cover to help slide them through would it affect the sound of the wires? Any recommendations? I don't want to damage the casing in case of future resale.

Lubricating oils depending on composition will affect the casing depending on the polymer they are made of. Is much safer to use soapy water or better graphite instead. Hope this helps
